+200 hp possible?

[elektrik]

dear friends,
is it possible to modify a 2.0l cu t4 block to get it so far that he delevers me more than 200hp? what chould me costs this? what modifications schould i do? offers (by mail please)?

the engine is for a bug from '69

[yetibone]

No.

If you could get that kind of power from an engine that size, thru forced induction, or nitrous, it wouldn't last long.

If you want that kind of power, a 2.4 litre fuel injected, Porsche cooled, exotic head havin', split lift and duration cam usin', nickisil cylinder havin' monster might get you right at 200 hp.

yetibone is right if you use a displacement that big it won't last more than a few thousand miles at best before you replace something criticle, I've seen a 2.9 lt. t4 that lasted about 30,000 miles but the guy was working on it three or four time a week...

Do your home-work on this one, elektrik, and you'll find something to fit your taste, but ask as many questions you need when talking to an engine builder, like how long should it last, is it driveable on the street, etc. Stuff like that and it should get you by!:)

If you plan on building it yourself, like me, find out what combinations of parts work best for the size engine you want. Also, if you build it yourself, don't be ashamed to let someone with experience do the tricky stuff that you may not be comfortable doing.

1971cc (2.0L) will have a particular combination of cam profile, valve size, rod length, and compression that is optimal for it's size.
2056cc will have a DIFFERENT combination of things that will work best for it's configuration. 2270cc has IT'S own build formula, 2316cc has its own, and so on.

Point being, you can't make a modified Type IV work efficiently unless you use the right combination of parts for the displacement that you want.

Check with an experienced builder of Type IV engines for some answers.

Good Luck!

well 200bhp might be pushing it,am in the process of building a stock bore and stroke 2ltr 44x38 vavles 45mm throttle bodies web 86c cam etc,etc and am hopeing for about 165bhp have been told this is about the limit for a 2ltr.and before any body tells me to build a bigger engine i need to keep under the 2ltr to stay in the under 2ltr class.
cheers rob

200 HP is more than possible, but don't think it comes easily..... It will take a 2316 at smallest to get you there in a sane manner.

Most engines need to be 2.5 L t think about making that power.

how fast en how many hp gat the engine standard? i wil that the car c'an drive 200km/h without any problem

[boygenius]

I think the 914 2.0 type 4 motor had 95 hp and 105 torque. My 1969 beetle would go 145 kph with 60 hp and 90 torque. It ran out of gearing when the valves floated at 4,000 rpm. Your top speed is dependant on your gearing.

Huh? :silly: :confused:

[elektrik]

i'ts a standard bug gear, maybee in the future I wille plaece a porsche transmission

by the way what doe I modiffy for safety? rolkage? 4points seat-belt with some sparco's or cobra seats? somthing els? random disk's break's? or only at front

[hybrid_john]

elektrik: Hey man, I think I know what your trying to say?!
If you wanna add a roll cage or some racing seat with four or five point harnesses, i'ts a good idea but it's completely up to you! If you plan on running with some disk brakes you can run them on either the front or the back, or maybe even both, just remember what ever combos you plan on doing is completely up to you!

You don't even have to run brakes if you don't want to!:silly:
But I wouldn't recomend it!;)

Where do you live that you can drive 200 km/h? What year and model is your beetle. Disc brakes are a good idea since drum brakes can fade from heat when stopping from high speed.:)

[hybrid_john]

Drum brakes can fade from high-speed stops, but, disk brakes can crack and smoke extremely bad from high-speed stops. I did that with my Sunfire coming down a steep grade going 80...:silly:

The front disk brakes cracked so bad that they shreaded the brake pads and ground down the drivers side caliper.

I will never go that fast with stock brakes again, which, brings me to my point. Is it possible that even though you upgrade to a Porsche brake system, that with the stock Porsche disk brakes they might crack and smoke the same?

Just wondering:D

But non the less, disk brakes are way better than drums.

Some people could break a pry-bar in a sand box. My friend cracked his 12" rotors in his car doing a 140 mph to zero. The stock porsche brakes mostly used are 944 parts and they were designed for a car that weighs 2,600 lbs. or more. So a 1,800 lbs. beetle really doesn't put that much stress on the brakes.:D

[elektrik]

for information my car is a 69 bug inported from holland to Belgium(case) chassis com from Belgium

i want to put somme 944 breaks ath te front en in te rear beetle breaks, the resson that i do this is because i buyed a new bug break cilinder, and it gives a good pression on the breaks with this combination

now i got a odder problem my gearbox that y revisated don't fit on my chassis my gearbox is mounted with 2 bolts ath te front but my chassis gat a mountaning plase with 3 bolds, how c'an i modiffy this?

thank you all for the great help assistanse

NAAAH! Porsche 944 brakes are made for a 2800lb car, a Super weighs a tad over 2100. Porsche brakes on any bug are just a shade under overkill.

Hummbug went thru 3000 hard miles before the machine marks wore off the rotors!

Yetibone

[hybrid_john]

Really.

Hmmm... I like that, it puts a warm fuzzy in my tummy:silly:

Okay, 15.000 miles with Pagid fastroad (stock) pads in 4pot Brembo's front and rear. Front pads look good for another 100.000 miles, front stock 951 discs worn ~1.8mm rear brakes no visible wear! Braking in my '03 Kab has been :silly: daily for nearly 2 years.

I have the confidence to whack the anchors at over 80mph on a dry road, no sweat.

Overkill? argument around here is well buried ;)
